The discovery opens up new ways to treat diseases aggravated by bugs that escape from the gut, says Lora Hooper of the University of Texas Southwestern Medical Center in Dallas.
"This work has uncovered some truly exciting new insights into the role of innate lymphoid cells in the gut, showing that they function like border collies that keep intestinal bacteria from escaping to other parts of the body," she says.
